LIN1024-3207 : Security Advisory - linux - CVE-2024-42084

Created: Jul 29, 2024    Updated: Aug 28, 2024
Resolved Date: Jul 29, 2024
Found In Version: 10.24.33.1
Fix Version: 10.24.33.1
Severity: Standard
Applicable for: Wind River Linux LTS 24
Component/s: Kernel

Description

In the Linux kernel, the following vulnerability has been resolved:

ftruncate: pass a signed offset

The old ftruncate() syscall, using the 32-bit off_t misses a sign
extension when called in compat mode on 64-bit architectures.  As a
result, passing a negative length accidentally succeeds in truncating
to file size between 2GiB and 4GiB.

Changing the type of the compat syscall to the signed compat_off_t
changes the behavior so it instead returns -EINVAL.

The native entry point, the truncate() syscall and the corresponding
loff_t based variants are all correct already and do not suffer
from this mistake.
